Abstract
The utility model discloses a limiting support of window opening, which comprises a cantilever and a bottom slot. A limiting block arranged in the bottom slot is articulated with the end of the cantilever, and the other end of the cantilever is articulated with a supporting piece. A strip-shaped hole is arranged in the bottom slot. A plurality of limiting holes are arranged in the strip-shaped hole. The limiting block is inserted between the strip-shaped holes and can slide along the strip-shaped hole. An offsetting spring is sleeved on the top of the limiting block positioned between the strip-shaped hole and the cantilever. When the top of the limiting block slides along the strip-shaped hole to the limiting hole, the middle of the limiting block is clamped in the limiting hole due to the upward spring of the offsetting spring, and the window is stuck because of the cantilever. When pressing the spring, the middle of the limiting block is downwardly moved, the top of the limiting block accesses to the strip-shaped hole and slides and the window is released from the stuck. When the limiting block is clamped in the limiting hole, the effect of the limiting is greatly enhanced, and the whole process of the operation can be achieved by slightly pressing the limiting block, which is quite simple.
Description
Technical field
The utility model relates to a kind of stopping means that is used for casement window, particularly a kind of limited support of windowing.
Background technology
When window is opened, need be fixed with certain opening angle, reach the effect of daylighting and ventilation, existing a kind of limited support, comprise cantilever and kerve and be installed in the interior limited block of kerve, limited block is provided with lock screw, limited block and cantilever end are hinged, an other end of cantilever is hinged with supporting spring, supporting spring is fixed on the window, supporting spring rotated thereupon when window rotated, and the limited block of cantilever drive simultaneously slides in kerve, reaches the fixedly purpose of window by turn lock screw fixed limit piece.This device mainly is to stop moving of cantilever by the frictional force between lock screw and kerve, thereby fixing window, when wind-force excessive, the thrust that cantilever is subjected to is during greater than frictional force, still can drive limited block and slide, produce very big inertia simultaneously, window is closed suddenly, the broken glass of shake brings loss easily; Fixedly often need very big power just can screw lock screw during window in addition, use inconvenient.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of good limit effect and the easy to operate limited support of windowing.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of limited support of windowing, comprise cantilever and kerve, limited block is installed in the kerve, limited block and cantilever end are hinged, an other end of cantilever is hinged with supporting spring, kerve is provided with bar hole, have several spacing holes on the bar hole, limited block is columniform three grades of boss, and its bottom external diameter is greater than the internal diameter of spacing hole, and the middle part external diameter is less than the spacing hole internal diameter and greater than the width of bar hole, the top external diameter is less than the width of bar hole, limited block interts in bar hole, and can slide along bar hole, and the limited block top between bar hole and cantilever is with back-moving spring.
The beneficial effects of the utility model are: cantilever is embedded on the kerve by limited block, when the limited block top when bar hole slides into spacing hole, its middle part is because of bullet on the back-moving spring, be stuck in the spacing hole, window is locked, and the middle part moves down when pressing down limited block, length of spring compressed, its top enters bar hole and slides along it, the window state that goes out of lock, and so forth.When limited block was stuck in spacing hole, the power that cantilever is subjected to was big again, can not make it mobile, so limit effect improves greatly, and simultaneously, all operating process only need be pinned limited block gently and can realize, and are quite simple.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a front view of the present utility model;
Fig. 3 is a sectional view of the present utility model;
Fig. 4 is the schematic diagram of limited block.
The specific embodiment
Referring to figs. 1 through Fig. 4, a kind of limited support of windowing, comprise cantilever 1 and kerve 2, limited block 4 is installed in the kerve 2, limited block 4 is hinged with cantilever 1 end, an other end of cantilever 1 is hinged with supporting spring 3, kerve 2 is provided with bar hole 5, has several spacing holes 6 on the bar hole 5, and limited block 4 is columniform three grades of boss, its bottom 41 external diameters are greater than the internal diameter of spacing hole 6, middle part 42 external diameters are less than spacing hole 6 internal diameters and greater than the width of bar hole 5, top 43 external diameters are less than the width of bar hole 5, and limited block 4 interts in bar hole 5, and can slide along bar hole 5, the limited block top 43 between bar hole 5 and cantilever 1 is with back-moving spring 7.During actual the use, supporting spring 3 is fixed on the window page or leaf, kerve 2 is fixed on the window frame, when window is closed, cantilever 1 overlaps with kerve 2, and when opeing the window, cantilever 1 moves and drives limited block 4 and slides on kerve 2 with window, when limited block 4 moves, slide in bar hole 5 in the top 43 of three grades of boss, this moment, back-moving spring 7 was compressed, when limited block 4 moves to spacing hole 6, limited block 4 is subjected to the effect of back-moving spring 7 and goes up bullet, its bottom 41 contacts with strip hole 5 place faces, and middle part 42 is arranged in spacing hole 6, because of the external diameter at limited block 4 middle parts 42 less than spacing hole 6 internal diameters and greater than the width of bar hole 5, limited block 4 just is stuck in and can't continues in the spacing hole 6 to move, cantilever 1 stop motion thereupon, window is fixed, and presses lower position block 4 gently, its top 43 moves down, enter bar hole 5 and slide once more, just stop up to next spacing hole 6, when window is fixed once more, its opening angle also with regard to conversion certain angle, changed lighting quantity and ventilation.
In addition, also be provided with fourth stage boss 44 above the top 43 of described limited block 4, be connected better effects if with cantilever 1 end by boss 44.Simultaneously, packing ring 8 is installed between back-moving spring 7 and the bar hole, back-moving spring 7 contacts with packing ring 8 like this, compares directly that to contact result of use better with kerve 2.Simultaneously, the number of the spacing hole 6 on the bar hole 5 is 3, can be 3 kinds of different opening angles after window is opened like this and fix, and spacing hole 6 also can reduce or increase, and the selection of the many more louver angles of number is also just many more.
Above-mentioned just the utility model preferred embodiment but should not constitute restriction of the present utility model, so long as adopt the technical scheme that is equal to the utility model also should be within the protection domain of the invention.
